ABSTRACT:
An eyelet-shaped type connector for connecting together opposite sides of a printed circuit board and having a first end section of a generally cylindrical shape extending out of one side of a hole in a printed circuit board and a second end section of a generally cylindrical shape extending out of the other side of the printed circuit board. A plurality of legs, bowed towards each other, connect the two end sections together. Because the legs are bowed inwardly they will give and become more bowed as the extended first and second ends are soldered to conductive areas around the holes in the printed circuit board and the board contracts after the solder has cooled, thereby eliminating cracking of the solder joints. The inside surfaces of the connector are coated with a soldering repellant material such as chromium and the outside surfaces with a solder attracting coating such as tin.
